kill the bacteria causing release of endotoxins e. kill human cells Is smallpox a DNA or RNA virus? How did viruses evolve? Imagine that a virulent (T_4) phage is inoculated with a Gram negative human bacterial pathogen. Explain whether the bacteriophage will have lytic cycle or lysogenic cy...
The synthesis of RNA using a DNA template is referred to as? Do bacteria have RNA in their genome like viruses do? What is the structure of RNA? Describe RNA. Chromatin is composed of: a) DNA. b) DNA and proteins. c) DNA, RNA and proteins. d) None of the above ...
A virus is made up of acore of genetic material, either DNA or RNA, surrounded by a protective coat called a capsid which is made up of protein. Sometimes the capsid is surrounded by an additional spikey coat called the envelope. Viruses are capable of latching onto host cells and getting ...
virion - (virology) a complete viral particle; nucleic acid and capsid (and a lipid envelope in some viruses) bacteriophage, phage - a virus that is parasitic (reproduces itself) in bacteria; "phage uses the bacterium's machinery and energy to produce more phage until the bacterium is destro...
As viral components are formed within a host cell, virions are created by a self-assembly process; that is, capsomere subunits spontaneously assemble into a protein coat around the nucleic core. Release of virus particles from the host may occur by lysis of the host cell, as in bacteria, ...
capsid proteins. They then underwent challenge infection with RSIV. Higher survival rates were observed in fish that received the 351R vaccine compared to the unvaccinated control group. A viral protein (351-R) was co-expressed with the bacterial glyceraldehyde 3-phosphate dehydrogenase as a fusion...
This ubiquitous protein is found in a diverse group of living organisms [36] and includes subfamilies of canonical ferritin, bacterioferritin found only in bacteria and archaea, and the smaller Dps. One of the major differences between canonical ferritin, and bacterioferritin is the presence of ...
Unlike bacteria, they are not free-living entities, relying on living host cells for their replication. Another relevant issue in food safety is that viruses are more resistant to environmental stresses, as well as to cleaning and sanitation programs, especially non-enveloped viruses, thus hamper...
What is a virus that infects bacteria called? What is the name for a virus that infects a bacterial cell? (a) What is a virus without a capsid called? (b) Describe the structure of bacteria. Antiviral proteins produced by virus-infected cells are called what?
Do viruses have cells? Which viruses regarded as being biologically important? Which type of T cells is most effective against viruses? What component of a virus is lacking in a cell? What organisms cause infectious disease? What is the difference in how a virus and bacteria replicate and affe...
